COMPOUND BE'VEL AND SQUARE.

Sl-ECIFICATION forming part of Letters Patent No. 718,344, dated January13, 1903.

Application filed August 9, 1902. Serial No- 119,026. (No model.)

To on whom, it may concern." I

Be it known that I, THOMAS VoLNEY HAMP- TON, a citizen of the UnitedStates, residing at Bowling Green, in the county of Warren.

and State of Kentucky, have invented a new and useful ImprovementinCompound Bevels and Squares, of which the following is a specification.

This invention is a compound bevel and square, the object being toprovide a tool particularly adapted for use for carpenters,shipbuilders, and millwrights by means of which they can accuratelygage'the length of a piece of timber or spoutingto be cut and also gagethe angle upon which the ends are to be cut, thereby making accuratejoints and avoiding all misfits.

Another object of the invention is to provide a tool of this kind bymeans of which work of this character can be more quickly accomplishedthan by any of the tools now in common use.

With these objects in view the invention consists in the details ofconstruction and novelties of combination and arrangement hereinafterfully described, and pointed out in the claims.

In the drawings forming part of this specification, Figure 1 is aperspective view of a tool constructed in accordance with my invention.Fig. 2 is a top plan view of one end of said tool, the sections beingfolded together and the beveled squares extended. Fig. 3 is a detailperspective view showing one end, the blades of the bevel squares beingfolded into the stocks. Fig. 4 is an inner face view of one end,illustrating the means of securing the stocks in their adjustedpositions. Fig. 5 is a similar view showing the stocks adjusted at anangle to each other, and Fig. 6

is a transverse sectional view taken on the line 6 6 of Fig. 2.

Broadly speaking, my invention consists of four bevel-squares orbevel-blades, each carried by a stock, said stocks being arranged inpairs hinged together, and each pair of stocks is connected by means ofan adjustable or extensible connecting-rod.

Referring to the drawings, A indicates the stocks or strips, which arepreferably made of hard wood, each pair of stocks being connected bymeans of hinges A. Each stock is slotted longitudinally, as shown at Aand pivoted in the said slot adjacent to the forward end thereof is thesquare or bevel blade B, adjustably secured by means of a set-screw B,which passesthrough theright-angular slot 13*, produced in the saidblade. It will, of course, be understoodthat each blade is adjustable inits respective stock, and each blade is of course independent of theothers. By having the stocks pivoted a variety of adjustments can behad.

In order to securely fasten the stocks in any adjusted position, Iemploy a plate 0, pivoted at O to the inner end of one of the stocks,the opposite end of said plate being slotted, as shown at C and throughwhich the set-screw C passes into the end of the other stock, the plate0 being angular in shape. This permits the stocks to be adjusted atvarious angles, and after being so adjusted they can be locked in thatposition by tightening the set-screw. The stocks are connected 'by meansof the adjustable or extension rods D, the outer ends of which arereduced or tapered, as shown at D, for the purpose of engaging thestaples or clips D arranged upon the upper face of the stocks. One ofthe rods D has a loop E connected thereto and through which the otherrod passes. A bail F, adjustable upon the rods, has a set-screw F forthe purpose of tightly binding the rods together after they have beenadjusted. A set-screw G also passes through each rod into the stock,thereby securely connecting each rod to its respective stock. The rodsbeing slidable upon each other, it is obvious that by loosening thesetscrew F they can be moved so as to bring the stocks toward each otheror away from each other after the distance has been gaged. The set-screwcan be tightened, and the tool will then be set in its proper position.In operation the connecting-rods are first adjusted so as to gage thedistance between any two points which it is desired to connect either bya piece of timber or spouting. The blades, together with the stocks, arethen adj usted so that the said blades will exactly indicate the angleupon which the ends of the timber or spouting are to be cut, andinasmuch as each blade and each pair of stocks is independent of theother it is obvious that any angle can be gag-ed, and by securing theblades and the stocks in their adjusted positions the tool can beremoved and placed upon the timber or spent to be cut and the exactlines marked upon said timber or spout, so that when the said timber orspout is cut it will fit exactly between the points which it is intendedto connect and all danger of misfit entirely avoided.

By constructing a tool as herein shown and described one skilled laboreris enabled to do the work heretofore requiring the services of two ormore skilled laborers.

Having thus fully described my invention, What I claim as new, anddesire to secure by Letters Patent, is-

1. A tool of the kind described, comprising two pairs of stocks, thestocks of each pair being hinged together, each stock carrying anadjustable bevel or square at its outer en d, the inner ends of eachpair of stocks being connected by means of an adjustable connection forthe purpose specified.

2. A tool of thekind described, comprising stocks hinged together inpairs, each stock having a square or bevel blade connected thereto, eachpair of stocks being provided with means for locking them in theiradjusted positions, and the extensible connection between two pairs ofstocks, for the purpose specified.

3. In a tool of the kind described, the combination with the stockshinged together in pairs, each stock being longitudinally slotted andcarrying a square or bevel blade, a slotted plate pivoted to the innerend of one of each pair of the stocks, the set screw passing through theslot of the plate into the end of the other stock of the pair, thesectional extensionq'od having tapered ends connecting two pairs ofstocks, the staples carried by the stocks adapted to receive the taperedends of the rod, and a bail and set-screw carried by the rod? allarranged and adapted to operate as specified.
